We're dividing 56478999 by 820 
We want to figure out the number of times 56478999 can be divided by 820.

Step 1:
820 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 820

Advancing to step 2:
The number 820 fits into 56 0 times, leaving a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 820

Advancing to step 3:
820 can be fit into 564 0 times, resulting in a remainder of 564.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 564 after subtracting 0 from 564.
Append the next digit (7) from the dividend to 564 and continue with: 5647 / 820

Advancing to step 4:
When dividing 5647 by 820, we get 6 with a remainder of 727.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 4920 from 5647, we get 727.
Bring next digit (8) of the dividend behind the 727 and repeat the process: 7278 / 820

Step 5:
7278 divided by 820 is 8 with a remainder of 718.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Deduct 6560 from 7278 and we're left with 718.
Bring next digit (9) of the dividend behind the 718 and repeat the process: 7189 / 820

Moving on to step 6:
If we divide 7189 by 820, we get 8 and a remainder of 629.
Record the quotient 8 as the next digit in the result. 
Result so far: 688.0
Subtracting 6560 from 7189 leaves us with 629.
Grab the next digit (9) from the dividend, add it to 629, then carry on: 6299 / 820

Going ahead to step 7:
When dividing 6299 by 820, we get 7 with a remainder of 559.
Use 7 as the next digit of our solution. 
Result so far: 6887.0
Deduct 5740 from 6299 and we're left with 559.
Bring next digit (9) of the dividend behind the 559 and repeat the process: 5599 / 820

On to step 8:
When dividing 5599 by 820, we get 6 with a remainder of 679.
The next digit of our result is 6. 
Result so far: 68876.0
The remainder is 679 after subtracting 4920 from 5599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Going ahead to step 9:
When dividing 6790 by 820, we get 8 with a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 68876.8
Subtracting 6560 from 6790 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 10:
820 can be fit into 2300 2 times, resulting in a remainder of 660.
The number 2 becomes the next digit in our result. 
Result so far: 68876.82
If we take 1640 away from 2300, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 11:
820 can be fit into 6600 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 68876.828
The remainder is 40 after subtracting 6560 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 820, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 68876.828
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
If we divide 4000 by 820, we get 4 and a remainder of 720.
Record the quotient 4 as the next digit in the result. 
Result so far: 68876.82804
The remainder is 720 after subtracting 3280 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 14:
If we divide 7200 by 820, we get 8 and a remainder of 640.
Use 8 as the next digit of our solution. 
Result so far: 68876.828048
Subtracting 6560 from 7200 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 15:
When dividing 6400 by 820, we get 7 with a remainder of 660.
Record the quotient 7 as the next digit in the result. 
Result so far: 68876.8280487
Subtracting 5740 from 6400 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 16:
820 goes into 6600 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 68876.82804878
Subtract 6560 from 6600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 68876.82804878, and the remainder is 4e-08.
